To all whom z' may concern: v

Be it known that we, FEDER J'. BUE and HnRvY M. TrDwELL, citizens of theUnited? State of America, residing at Pomeroy, in the county of Garfieldand State of Vashington, have invented certain new and uscfulImprovements in an Apparatus for Steaming Material, of which thefollowing is a speciiication, reference being had therein to theaccompanying drawing.

This invention relates to an .apparatus for steaming material such asbeans and the like, and has for its object the production of a simpleand efficient mechanism for softening and partially cooking the beansprior to passing the same to the rolls. l

Another object of this invention is the production of a simple andefficient means for causing the beans to pass through a steam filledreceptacle and in this way become softened and partially cooked.

Other objects and advantages of the present invention will appearthroughout the following specification and claim.

In the accompanying drawings:-

Figure 1 is a side elevation of the bean softening mechanism.

Fig. 2 is a central vertical section through the structure shown in Fig.1.

Fig. 3 is a section taken on line 8-8, of Fig. 1 looking in thedirection of the arrow.

By referring to thevdrawings it will be seen that 1 designates the outerwall or cylinder, which is rovided with a steam inlet aperture 3, wlthinwhich aperture 3 fits an inlet pipe 4. An inner wall 2 is placed withinthe outer wall 1 and is held in spaced relation thereto by means of the'ller bands 5 fitting between the walls 1 and 2 at the upper and lowerends thereof.

The wall 2 is provided with a plurality of apertures or ports 6 forpermitting the passage yof steam through the wall 2 from the inlet pipe4L.

A steam discharge or distributing pipe 7 is positioned centrally withinthe inner wall 2, and this steam discharge pipe 7 is provided with acone-shaped upper end 8 for constituting a means for shedding the beansand causing the same to drop upon either side of the steam pipe 7. Thepipe 7 is provided with a plurality of steam discharge apertures 9 forcausing the steam to be discharged from the pipe 7 and across and intothe inner portion of the receptacle, the steam then passing out throughthe bottom Specification of Letters Batent. l

of the heater. A plurality of bracing bars 10 are securedto the innerface of the wall 2 and to the outer face of the steam pipe 7 toconstitute a brace therefor. A plurality of steam inlet pipes 11 aresecured to the pipe 7 diametrically opposite to the lbraces 10, and bymeans of the pipes l1 and braces 10 it will be seen that the pipe 7 willbe eiiciently supported in its proper position. The pipes 11 areconnected to the pipe 7 near its upper and lower ends, and the oppositeends of these pipes 11 are connected to a vertically extending pipe 12,which pipe 12 is also connected to a steam supply pipe 13. The steamsupply pipe 13 may be connected to any suitable heating coil or othersuitable means which may be employed without departing from the spiritof the invention, for it is not desirous of limiting the presentinvention to any particular or specific form of heating means.

A cover 14 is placed upon the top of the steaming receptacle and isprovided with a depending annular ange 15 fitting over the upper edge ofthe outer wall 1 as illustrated in Fig. 2. The cover 14 is also providedwith an linner depending collar 16 which is adapted to rest upon theupper edge of the inner wall 2. The cover 14C is provided at its upperend with a spout 17 which spout is connected to the usual bin fordischarging beans down into the steaming receptacle.

From the foregoing description it will be seen that as the beans aredischarged down through the chute or spout 17, the beans will fallthrough the inner receptacle 18 formed by the inner wall 2, and thesteam discharged from the apertures 9 and V6 will be considerablycondensed and passed out through the bottom vof the heating receptacle.By the beans falling down through the entire length of the innerreceptacle 18, it will be obvious that the beans will be considerablysoftened by the steam and also partially cooked, by means of thesuperheated steam through which the beans fall.

Having thus described the invention what is claimed as new, is:-

An apparatus for steaming material comprising an outer cylinder, aninner wall provided with a plurality of closely arranged perforations,an inlet pipe communicating with said outer wall and adapted to supplysteam to the space between said inner and outer wall for forcing steamthrough the apertures formed in said inner wall, a cenratented oet. ic,1917.

trally locatedstean pipe braced and sup-- ported centrally of saiolinner Wall, said centrally located steam pipe provided with a pluralityof closely arranged` perforations,

a steam supply pipe communicating With said inner wall whereby grainclroppecl 1f) through said apparatus Will be acted upon by a series ofoppositely opposed jets of steam.

In testimony' whereof We hereunto aHix our signatures. y
